A Map of Colombia with its neighborhood countries. B Boxes of the median of RNA copies and bars of individual symptomatic patients and asymptomatic subjects with RNA copies. Asymptomatic data. Median = 6003.985; P25 = 2152.519; P75 = 16,780.655. Symptomatic data: median = 12,652.686; P25 = 2813.048; P75 = 26,288.189. Extreme values were excluded, red spot outlayer extreme. The median RNA copies for symptomatic was 12,652.6 (IQR 2813.0–26,288.1) and for asymptomatic 6003.9 (IQR 2152.5–16,780.6). C X-axis internal patient’s code number, Y-axis Log by RNA copies/ml of symptomatic and asymptomatic individuals, the average of symptomatic was higher than asymptomatic patients. Several asymptomatic patients show higher RNA copies than some symptomatic patients. Confirmed patients a and b resulted in 2 and 6 infected contacts, respectively. Asymptomatic individuals c and d resulted in 5 and 4 asymptomatic individuals, some of them with important RNA copies. The average of symptomatic was higher than asymptomatic. A remarkable data that 15 health workers resulted infected in order according to viral load (symptomatic = 556, 593, 594, 595, 602; asymptomatic = 583, 585, 592, 674, 677, 678, 682, 600, 601 and 604)
